According to foreign media sources, battery suppliers Thai Storage Battery (3K Battery) Daimler-Benz has received the battery supply contract. From 2012-2016 the supply of 500,000 Mercedes-Benz auxiliary battery.

3K Veerawin Korphaibool vice president, said this is the first 3K with foreign car manufacturers signed a contract because the 3K is usually common to the domestic supply of Volvo and battery.

3K announced first half sales of 30.6 billion baht ($ 102.6 million), up 34.2% in the first half net profit of 217.4 million baht (U.S. $ 1 = 29.84 baht), while the first half of last year, a loss of 1.95 million baht.

3K Battery expectation this year sold 1.5 million batteries, worth 5.7 to 5.8 billion baht, up 10 percent over last year.

Chinese-American scholars have recently invented an organic semiconductor materials, thin flexible material which is to explore new research found. Such fast conductive material, soft and durable features, is expected to promote light and easy to carry foldable electronic product development.

Department of Chemical Engineering at Stanford University associate professor of Baozhe Nan has been in use chemical knowledge and methods to develop new materials, she has invented the artificial electronic skin soft and sensitive solar cells can be stretched.

Bao Zhenan accept China news agency reporters in the interview that the electronic products used in inorganic materials such as silicon, with conductive fast and strong advantages, but bulky, heavy weight, easy to break but it is inevitable Achilles heel. Use of personal electronic products carrying more and more common to find alternative materials is imperative. New organic semiconductor materials, conductive invented fast, good flexibility, lightweight and durable, can be used to make television and computer displays, electronic circuits and so on.

With the current production of LCD TVs and computer monitors the main material of amorphous silicon, this new material is amorphous silicon conductive speed of 30 times. Baozhe Nan said, still some distance to the actual use of time. Although it’s a good conductive properties, but solubility is not satisfactory, further research and improvement. “I hope that with the way the industry to manufacture products combine the production of non-vacuum environment, such as the soluble ink made ​​with the printing of large-scale production methods.”

Recently, U.S. scientists have developed a new method create a piece of button battery, which provided by the butane fuel, run time is the same weight of lithium-ion battery 4 times, when the power runs out, simply by adding a small amount of new fuel, will be able to immediately to the battery. They also create another one by a radioactive decay provide heat to the battery, it can continue to generate electricity for 30 years, do not add fuel does not need maintenance, implementation time is expected to become the ideal space flight mission equipment power.

Massachusetts Institute of Military Institute of Nanotechnology engineers Horowitz said that tungsten is the main raw material for the new battery in the etching of the tungsten surface billions of nano-sized pits. When the tungsten absorbs heat, regardless of the heat from the sun, hydrocarbon fuels, is the decay of radioactive isotopes or other sources of heat, light will be issued, and emission spectra are constantly changing, as each pit as a resonator, can release specific wavelengths.

U.S. Department of Energy Information Management Center data show that the energy used today, 92 percent of energy needs through the heat into mechanical energy into the process longer. However, the efficiency of existing mechanical system is relatively low, and can not be applied to reduce the size of the sensor, smart phones or medical monitoring equipment.

Sony announced that it will use tin (Sn) negative electrode material to improve the capacity of lithium-ion rechargeable battery. The development of the “18650″ size (diameter 18mm × high 65mm) of the cell, the capacity of up to 3.5Ah. With the company in 2010 compared to the original production of 2.8Ah capacity significantly increased by 25%. Scheduled to begin shipping during the year 2011.

 In fact, this is not the first time that the negative use of Sony lithium-ion rechargeable battery of Sn of their products. The company started in 2005 for the camera from the sale of the diameter of 14mm × 43mm high, “14430″ size battery cells. The laptop will be in volume production for a large circle of more than 14430 18650 size products.
 
The development of lithium-ion rechargeable battery has a positive and improved diaphragm. The cathode material by the capacity and safety of both the ternary class (Li (Ni-Co-Mn) O2) material into a lithium cobalt oxide (LiCoO2). Co in LiCoO2 material prices higher, and thermal stability at a disadvantage, so the cathode material has been directed triple class changes, but Sony was against the tide, using a higher capacity of the LiCoO2.

LiCoO2 in an internal short circuit or other abnormal temperature rise, this case will produce oxygen, oxygen reacts with the organic electrolyte may burn. Therefore, Sony LiCoO2 particle surface “in the 0.1 ~ 1μm thick coating process” (Inoue). According to the company, this approach can reduce the reaction of oxygen with organic electrolyte.
 
Diaphragm, in order to prevent internal short circuit, micro-porous polyolefin membrane in the formation of a few μm thick on both sides of the metal oxide ceramic layer (Figure 3). Ceramic layer with three-dimensional structure, the diameter of the metal oxide particles less than 1μm and a mesh-like adhesive resin was connected. When an exception occurs, the higher flexibility and adhesive resin network that allows insulation around the metal oxide attached to the foreign body, thus limiting the current through.

Membrane on both sides to form a three-dimensional structural ceramic layer. Once mixed with metal foreign bodies cause membrane damage, ceramic layer will transfer to the surface of metallic foreign body to prevent a large current through. (Figure from “Nikkei Electronics,” according to information drawn Sony)

Of course, the new unit there are also issues. For example, the repeated charge and discharge 300 times after the initial capacity will be reduced to about 80%. After repeated charge-discharge capacity of 500 will be reduced to about 60%, available only managed to reach the minimum standards used in notebook computers.

Most products maintained rapid growth in the statistics of the 86 kinds of main products, there are 67 kinds of positive growth. Among them, the top four are solar battery, plastic products, feed and ferro-alloys, solar battery with 101.8% growth rate in the first place.

July 24, security chief of the laboratory consultant company Accuvant • Charlie Miller found that the Apple laptop battery chip security vulnerability, and thus vulnerable to hacker attacks, data theft even lead battery scrap.

Will be held in August in the “Black Hat conference,” Charlie Miller, plans to • people report an attack on Apple’s new notebook computer method, which uses a battery of security control weaknesses exist in the chip.

Modern laptop batteries have a capacity to monitor the level of micro-controller, it helps the operating system and recharge the battery charger detection. The chip makes the lithium batteries, even when the computer shuts down can also determine the destination charge, and can adjust the heat to the battery to ensure their safety.

However, in the detection of some of the Macbook, Macbook Pro and Macbook Air laptop computer batteries, Miller found that they are vulnerable to attack. Batteries at the factory with the default password, just cracked the password can control the chip firmware, and may make any hacker attacks, can cause permanent damage to the battery, malicious software can secretly to infect the computer, or even cause the battery to overheat, catch fire or explode.

In order to solve the Macbook battery problems, Apple released in 2009, software update, Miller through its analysis, found the two groups can be used to enter and modify the Apple battery password. With the password, he soon will be able to reverse the transformation chip firmware, free to manipulate the operating system and charger for the chip to read the data, or even completely rewrite the firmware.

Therefore, the battery becomes effortlessly can not be recognized by the computer - Miller has easily scrapped 7 cells (the total value of about $ 130). He pointed out that from the criminal point of view, even on a chip installed in the persistence of malicious software, as other parts of infected computers, steal data, function control and even let the computer crash. When checking the source of infection, few IT managers will think the battery firmware, so the chip can be repeated undetected malware infected PC.

In addition, to carry out such attacks, they need the chip and the interface between the operating system to find another loophole. But Miller seems that this is not a difficult one. “May it never be regarded as an attack entry point for Apple, so it may be easily compromised.”

Then the hacker may be to detonate by remote control batteries? Miller did not do so, but he believes this is possible, he said: “test in my own home, so I do not want to cause an explosion there.”

Miller said, some researchers suggested that he not continue the study of the battery, because it may be too dangerous. However, Miller found that for their own problems have solutions. He plans to held in August this year, “Black Hat conference,” released a product called “leak-proof gun” (Caulkgun) tools to help Apple users to change their battery firmware password random sequence, thus preventing him from ever conducted that the factory password for the attack. Miller also reflect his findings to Apple and Texas Instruments, to arouse their attention on the vulnerability. And Apple has not yet made any response to this.

The end of 2010, Changzhou Trina Solar Limited sales Pobai billion. But with the policy of European countries gradually reduce the subsidies, the PV market in 2011 was generally look bad.

After experiencing rapid growth in the next 10 years the PV industry will enter a second phase, the growth rate will not soar, but become more rational. However, the high discipline where it did not show much concern, “Last year, TRW’s sales in the global market for the 1.06GW, this component is expected to sell 1.75-1.8GW.”

PV industry now and in the growth stage, which is not in doubt. But the growth rate is gradually declining trend, but every year there may be some fluctuations. But this is not entirely because of subsidies decline. For example in Germany, in 2004, FIT (solar electricity price subsidies), the decline in subsidies every year. This is inevitable, if not decline, the industry’s contribution to society would be impossible. Long term, the cost of photovoltaic power generation side of the user should first achieve power parity, the parity after the realization of the power generation side.

The first echelon of several suppliers, including China and Japan, Europe, the United States, some companies, its sales accounted for 40% -50% of global share. The remaining twenty-three tier companies accounted for over 50 per cent.

In general, one tier of business approved by the bank, the customer groups are also large energy power company, or long-term investors, their needs and policy adjustment will not produce great changes. Customer base, which is really a group of opportunistic investors are directed at the high policy of subsidies to do, but their docking are generally twenty-three tier enterprises.

Challenges of the future is if energy storage battery technology can not keep up, then the solar energy development will be restricted. Solar energy is now an important part, and only accompanied by energy storage technologies, especially the size of energy storage technology, solar energy could become a major part.

PV industry is actually a human through technological innovation to create value. Recommended that the Government strive to foster a competitive industry well-known enterprises, such as Japan in the 1970s, the global leader in the appliance industry, companies such as South Korea’s leading companies in the semiconductor industry. Photovoltaic industry to become the pride of Chinese industry, must have such a position.

Solarbuzz U.S. companies to disclose, the United States is non-residential solar battery projects over 17GW. Reduction of feed-in tariffs in Europe subsidies, the U.S. surge in the project, “has become the expected growth rate is higher than any other region of the world markets in the world” .

Solarbuzz said the U.S. plans to set up a capacity of 50kW ~ 500MW system, scheduled second half of 2011 to 2015 a total of 601 projects installed. 17GW of projects divided by state, California, about 62%. The reason is that the state set “renewable portfolio standard (RenewablePortfolioStandard: RPS)” target up to 33%.

In the 17GW of projects, the development of the top 12 companies accounted for 49% ratio. Solar cell modules have been selected from the project point of view, the top three suppliers of modules for the U.S. First Solar, SunPower and Suntech China power the United States. Top-ranking supplier of inverters for the U.S. AdvancedEnergyIndustries and the United States SatconTechnology.

According to reports, the U.S. solar module factory supply price in the past four months have fallen sharply. Its influence has begun to spread to large-scale projects the price. 1MW system projects the average price above $ 4.50 / W , and 32% of project price $ 4 / W (DC output) below.

July 12 evening news, Kyodo News reported, Sony Shigeki Ishizuka, senior vice president, said on Tuesday that Sony is working with domestic and foreign car manufacturers to discuss, want to start manufacturing from 2015 lithium-ion batteries for electric vehicles

He said that Sony battery electric vehicle demand is expected to show substantial growth, maturity if the market demand, the company will consider the plant, including an overseas factory.

He also said that Sony also plans to develop gas-electric hybrid cars and plug-in hybrids use the battery.
